• In recently years, more and more infill producers have been put into production with poor cement job quality. Aiming at improving cement job quality, a research on method of assuring cement job quality based on adjusting formation pressure has been made in third infill wells in Xing-11 Development Area in Daqing Oilfield. Based on a new research result on formation pressure difference affects cement job quality and geology characteristic of Xing-11 Development Area, theoretically, it is sure that interlayer pressure difference must be controlled less than 6MPa to get a good cement job quality. On the basis of understanding sediment characteristic of tabulated thin beds and untabulated beds, a research method of analyzing and predicting formation pressure is developed in a certain development area, theoretical model and resolution model of pressure distribution is established, the method of knowing single well pressure and predicting single layer pressure was given. According to the predicted result of formati
