3D Visualizing Technology of Well Planning and Well Path Calculation for Directional and Horizontal Wells

With the development of deep drilling and 3D exploration recently, 3D directional wells and 3D horizontal wells have been being popular quickly. This paper made an introduction about cluster well technology adopted by joint venture on south China Sea. Mainly, it showed the software, control of well path and emphasis on drilling operation in different sections. Analysis on present situation of directional techniques and software utilizing onshore China, and find out the gap between onshore drilling at home and advanced directional software abroad. It presented the software named Navigator in which planning line of thinking and calculation ideas were displayed. It also studied which problems should be resolved in planning stage, and optimum results could be achieved, and which parameters should be calculated so that the directional driller could have most convenient helps in drilling operation. Finally, two examples, a proposed sidetrack program and projection on target, were presented separately .
