Research Of Wireline Logging System

1.The main work of this paperWell logging technique of quick development to measured well to collect software to put forward new of request, for the sake of feat Well logging new technique of development, with new number control to collect an equipments to match each other a set, development 1 set have independence intelligent property right of, integrity measure well engineering management to collect processing for the software platform of the collect of integral whole system.The main research contents include:(1)Well logging sample system software a realization a method of analysis research;(2)The development is complete open of Well logging data to collect a software mold piece and measure piece and ground of the well instrument service mold to pick up a people a mold piece(include an equipments to drive);(3)Curve solid hour manifestation way of research and realization;(4)Make use of forerunner of document management way, Well logging activity to divide the line into engineering, homework, well segment...etc. to carry on management, simplification data document management of complications degree, exaltation produce efficiency;(5)Solid hour data exchange way of research;(6)The development"soft show a machine" function, with sketch direct observation Well logging instrument of collect data and appearance(7)DevelopmentWell logging data solid hour the backup function mold piece, prevent°from a data accident throw to lose;The establishment"black box son" function mold piece, carry on supervision towards Well logging operation.The main workload of completion:(1)Well logging collect the total structure design of the system software;(2)Design and data of the data structure of each software mold piece connect of design;(3)Well logging collect a data of solid hour saving;(4)The data dispatch and the result output.Key technique:(1)The large solid hour data collect system of solid hour, credibility.(2)Face to software design and engineering of object management.(3)Go deep into the pit in the Windows 2000/XP understanding.(4)Provide to measure the supervision function of the well whole process.Innovation point:(1)Make use of data for the memory built-in eXtremeDB of the database system to carry on solid of exchange, then come to a fast data exchange of purpose, again make use of database system easy operation and maintenance of advantage;(2)Provide to measure the supervision function of the well logging whole process, in the system constitution operation record of function, integrate the affairs of windows system management system, make use of the windows affairs look into a machine and can look into;(3)The manifestation inclined well's alignment and track in underground by keeping view sketch, for description the oil well information provide thorough credibility of data.2 measure well real-time data collect system of design2.1 The characteristics of software system Should database for software system to make use of solid etc. new of way exaltation the data collect with processing of efficiency.The curve return to put function not only provided a variety reference treatment for the operator, and at experiment instrument of time the instrument descend the data that the well obtain at a time can satisfy variety experiment method, economy a great deal of time and cost.At add new instrument of time, add a dynamic state conjunction database, need not modification with add a great deal of code, shortenned instrument to go together with to connect with experiment of period.Assurance the data collect of stability, decrease the workload of operator, exaltation well logging time limited efficacy.Is later of well logging to collect software a development to provide template and method.2.2 The real-time data collect the data of system exchange of researchReal-time data collect software of main work is while well logging construction to instrument collect of the geology information carry on record, analysis, conversion.Solid hour data of exchange is BE the whole software system realization basic function of foundation and core.. Real-time data be main to obtain from the hardware equipments of originality the curve data of the data and processing empress.This two kinds of processing of data with break very multifarious, but direct to the memory data carry on an operation again very complications and easy come amiss, therefore adoption eXtremeDB database system.The eXtremDB is a database system(IMDS) with built-in memory, should the database be applicable to various built-in system and other demand high performance, baby size, close saving, zero memory allotment or a few attribute and have of application realm.Conduct and actions a memory type database, the eXtremeDB picked and get rid of complications but expensive document management to alleviate to save management mission.This brought the following what time advantage:Show Zhao ground the code of which shortenned application procedure and data path;Can pass decrease CPU instruction with full make use of have already have of space to saving more data be excellent to turn function. Is shown as diagram above, the real-time data is divided into 2 kinds:The curve data that get after connect the originality signal that a people collect and through instrument service the procedure from the hardware.Therefore, in real-time the data the commutation, demand establishment two pieces are according to the object:The originality data buffer area and the curve data row form.What the originality data buffer area deposit is the electronics signal that the hardware connect the well that a people provide to descend instrument data, provide to each instrument mold piece usage.To instrument service procedure to say, every time demand latest of data pack then, therefore, originality data buffer area can is fix size.When the hardware connect via the new data, press appointed the position amiable preface write in buffer area, then hair the data break news procedure to the instrument service.When hardware connected to receive a data next time the hardware still press homology in proper order and the position write in, again hair news, such circulation bottom go to.What the curve data row form area deposit is the curve data that the instrument service provide, all data will use in wholely solidly the hour the data collect, therefore, it of size should is dynamic state of.Get number and size of curve when the system adjust form into the instrument service, can get every time the curve break space size in the district for use.When the instrument provide a set of new of data, the curve data row form area first application all curve length with of space, then write in a curve data.Curve manifestation etc. service procedure can usage latest of one suite line data, can also from appointed the position get many suite line data.3.conclusionThrough the spot experiment with expansion, software terrace can full satisfy well logging the spot the data collect with processing of demand, match operator of operation habit, in keeping with well logging engineering of development and trend.
