Matching Technology Of Horizontal Wellbore In Maling Oilfield Mining Machine

Since the80’s of the last century began after the application of horizontal well in the oilfield, has become an important symbol of the efficient development of oil and gas field. Oiltwo factory of horizontal wells in the past two years the number increased year by year, due tothe characteristics of high yield, the wellbore of horizontal well with horizontal section and soon, need to establish the system of matching technology of horizontal wellbore, is from thethree pumping equipment optimization, optimization of production parameters, wellborematching process, fine daily management etc., the establishment of technical series adaptationand production characteristics of horizontal wells.Because the production of horizontal well is longer and lower level structure, fishingdifficult fall fall into the bottom of production or operation, and the operation cost is high; thehorizontal segment of the sand washing is more difficult, the need to use the chamfer tubing;horizontal perforation site, sampling water heavy workload, long time. Therefore, this paperfocuses on the working principle of FOPS device and a new sampling water locating device tostart, system analysis, overcome the defect of other similar methods, development of new antilitter device and sampling water device, and through the laboratory experiment and field test,verify the design performance and use string falling device and water sampling deviceprotection tube. According to the test, optimization design of anti pipe string falling device andsampling water device, the formation of the mechanical structure is applicable and the use oftechnology, effectively solve the water problem of fall and horizontal section protection tubecolumn, with a larger field application value and application of high efficiency.
