Title: APPLICATION OF HORIZONTAL WELL TECHNOLOGY IN BOTTOM WATER AND HEAVY OIL RESERVOIR OF BLOCK XINHAI 27
Abstract: With the progress of oilfield development technique, the production technologies of horizontal well are getting more and more perfect. These technologies are widely used in bottom water reservoir, vertical fracture reservoir, heavy oil reservoir and low permeability reservoir, and bring into obvious economic benefit. D1 reservoir of Block Xinhai 27 is a typical bottom water reservoir. Over 10 years development with vertical wells, it has entered a high water cut period of development. The effect of development and adjustment with vertical wells is not good, as a result of bottom water coning more seriously and water cut rising faster. Therefore, 3 horizontal wells have been drilled on the basis of research on the geologic characteristic of reservoir and the distribution of remaining oil. After putting into production, the effect is comparatively good, showing a high initial productivity and low water cut. Oil production rate has greatly been increased.
