The utility model relates to an integrated cross joint generally used in well drilling well completion formation testing and oil production process, which is composed of a cross joint body, an upper and a lower flanges, and wing pipes communicated to the cross joint body. Through-holes penetrating from top to bottom are provided in the cross joint body, symmetrical horizontal through-holes communicated to the through-holes are also opened on the middle lateral wall of the through-holes, wing pipes are connected on the horizontal through-hole, two flat valves are arranged on the left wing pipe, screw thread flange is arranged on the outermost end. Two flat valves are arranged on the right side pipe, thread flanges are arranged on the outermost end, and an instrument flange is loaded between the two flat valves. Upper and lower flanges are respectively provided on the upper and lower terminals of the cross joint body. The utility model not only cuts down the wellhead non control and wellhead flare-up safety risks during the exchanging and penetrating wellhead operation process and potential safety hazard of falling object to damage human, for providing an effective guarantee of well control safety of drill absorption well completion operation, saving the wellhead exchanging time, and improving the well completion ageing effect.
