The Research On The Distribution And The Development Of The Remaining Oil In Thick Oil Zone Of Lamadian Oil Fie

On the basis of thick oil rock's fine geology research, take advantage of all the kinds of performance and static data, because there are a lot of causes those can affect the remaining oil's distribution, and the causes are very complex. The experts often adopt the synthetical method to analyze where we can find the remaining oil, the distribution of the remaining oil can be evaluated qualitatively. And because most of the wells have no the interpreting data about their watering zones except some new drilling wells and some old oil wells, it imposes a lot of difficulties on the research of the distribution of the remaining oil hi the thick oil zone. How to take advantage of all the kinds of performance and static data, for example, the data of all the zones, the explaining data of the wartering zones.On the basis of thick oil rock's fine geology research, take advantage of all the kinds of performance and static data, and adopt the method of "research the plane first and then the vertical .research quality first and then the quantity ," that is first set the relationship that all the kinds of main elements those affected the planiform and vertical watering-out are subordinate to the watering-out degree . Using the method of comprehensive judgement to distinguish qualitatively the planiform watering-out degree of the estimated well dot as these three degrees: the higher, low and unwatering-out. On the basis of planiform watering-out's judgement, and then distinguish qualitatirely the planiform watering-out degree of all the the deposit unit and all the well as these three degrees: the higher, low and unwartering-out . Then, using the watering-out data of drilled inspection chamber to set oil saturation that hi the different watering-out degrees, on the basis of it, work out the equal value of unit are a remaining oil of all the wells , at last we can work out the remaining oil of all the deposit unit, and value the potential and the distribution of the remaining oil of all the unit. At the same time , it analyses the affective elements of remaining oil's plane and vertical distribution from the angels of geology and development , and have a conclusion about the type of plane and vertical distribution of the remaining oil . it brings out adoptable method that used to excavate the latent power according to different types of remaining oil that hi the thick oil rock through combining all the skills and methods of development . For this problem we put forward five kinds of measure and methods, those are:The first, thicken the wells in the bad oil zones in order to develop the remaining oil of the deposit sand zone.The second, dotted the wells to develop the remaining oil of the thick sand zone.The third, perfected the relationship between the injection well and the oil well to develop the remaining oil of the other zone.The forth, perforating the zone to develop the remaining oil of the zones that has isolated zone.The fifth, enhancing oil recovery to develop the remaining oil of the zones that has no isolated zone.
