Research On Optimization And Evaluation Of The Adaptability Of Well Completion Fluid Of Kuche Area Tarim Oil Field

With the continuous development of contemporary oil and gas exploration and development technology,especially drilling technology in complex formation,deep,ultra-deep well and the special oil and gas well,the drilling and completion fluids′important position in drilling and exploration is more significant,which has been recognized as "blood" of the oil and gas drilling and exploration by domestic and foreign oil and gas companies.it is one of the core technologies,and plays a vital role in oil and gas exploration and development and drilling and production operating.Completion fluids technology plays a very important role in drilling technology of the protection of reservoirs.Firstly,this paper researches on the optimization of completion fluids blocks application,taking the Kuche area fluids system applications wells in Tarim Oilfield as the research object.This paper describes the research status of completion fluids,technical difficulties and research status of three high completion fluids in Tarim oilfield,providing the direction for optimization of completion fluids blocks application.Secondly,thorough extensive investigation,based on a large number of experiment in laboratory,this paper gets a new completion fluids system and other optimization evaluation dates.According to the completion fluids field application in Tarim Oilfield,this article proceeds laboratory evaluation,creates a new a new completion fluids system,and analyzes the main treatment agents,features,formulations and recommended performance indicators,then evaluates the new completion fluids application in the oilfield.Finally,through comparing the effects in adjacent wells using new completion fluids to evaluate the new fluids,this paper gets the advantages and disadvantages of different blocks by using different completion systems,then selects optimum completion fluids to different tectonic blocks.
