在伟大领袖和导师毛主席的《实践论》和《矛盾论》光辉哲学思想指导下,我们对正在钻井的地区,其钻进过程中遇到的地层漏失和随之而来的漏失卡钻问题,做如下初步分析:我们油田的上部地层(包括平原组、明化镇组、馆陶组)地层松软,胶结性差,渗透性强,承压能力较小,新钻井眼当泥浆未造壁前或破坏了已经造壁的井身时,就容易引起井漏并导致井壁坍塌,发生卡钻。一般造成漏失的压力,多在高于正常循环泵压40大气压以内。
Guided by the glorious philosophical thinking of “Practice” and “Contradiction” between the great leader and Chairman Mao, we have discussed the problems of formation loss and subsequent slip stuck during the drilling process in the area under drilling , The following preliminary analysis is made: The strata in the upper strata (including the plain group, the Minghua group and the Guantao formation) in our oilfield are soft and have poor cementation, strong permeability and small pressure bearing capacity. Or destroyed the wellbore wall has been made, it is easy to cause leakage and cause the shaft wall collapse, stuck. The pressure caused by the loss, usually higher than the normal circulation pump pressure of 40 atmospheres.
