The application procedure of preflush for well cementing 油氣井注水泥前置液使用方法
Study and application of biolngical oil displacement agent in cementing pad fluid 生物驅(qū)油劑用于固井前置液的研究與應(yīng)用
The application of prepositive acid fracture technique in the reform of carboniferous oil reservior 前置液酸壓技術(shù)在石炭系油藏改造中的應(yīng)用
Then it gives some suggestion on the determination of operation discharge and preflush rate and some technical problems in operation 通過實際施工資料的統(tǒng)計,對施工排量和前置液量的確定等施工中需要改進(jìn)的技術(shù)問題,提出了建議。
Aiming at some reservoir characteristics of low porosity , extra - low permeability , low oil saturation , and low productivity as well as shallow depth in changxi area of ansai oilfield , through a large number of laboratory experiments and field tests , some suitable fracturing technology and operation parameters have been optimized , including low temperature fracturing fluids . , propping fracture radius 、 pre - liquid and sand - fluid ratio 摘要針對安塞油田長西區(qū)低孔隙度、特低滲透率、低含油飽和度和淺層低產(chǎn)的油藏特性,通過大量室內(nèi)、現(xiàn)場試驗研究,優(yōu)選出適合的壓裂施工參數(shù),包括低溫壓裂液、裂縫支撐半徑、前置液和砂液比。
