China appears to be planning to send a delegation to examine U.S. made pertroleum equipment, according to reliable sources.

After Communist Party Chairman Hua Kuo-feng made a speech earlier this month calling for significant expansion of China's oil production, Peking moved to arranged a summer visit.

The invitation to the Chinese was extended by the Petroleum Equipment Committee of the National Council for U.S.-China Trade. China has not selected its delegation, but probably there will be about 10 experts in drilling and other technology related to extracting oil and gas.

An official of the trade council, which will host the Chinese, declined to comment yesterday on the ground that final arrangements have not been completed.

China's decision to send its first team of experts in oil and gas extraction to the United States reflects a determination to press ahead to become at least a meodest oil exporter, an American expert said.

China recently talked to Japan about reviving an oil agreement and hopes to provide Japan with 15 million tons annually in the 1980s.

It is also expected here that China will push its search for oil in several new areas, including potential offshore fields in the SOuth China Sea and perhaps the East China Sea.

U.S. petroleum equipment is generally acknowledge to be the best in the world, and some technology foe extraction of petroleum can only be purchased some U.S. equipment from Texas companies and bought two large oil rigs that utilize American parts from a Singapore shipyard.

If tentative plans for the Chinese delegation are followed, it will stay in the United States four to six weeks and visit more than two dozen American companies. Delegation members will meet with other corporation representatives at receptions and other functions bringing them in contract with as many as 100 U.S. firms, according to preliminary programs.

Former Vice Premier Teng Hsia ping was criticized last year for pushing oil production with the goal building a sizable export capacity.

China is returning to many Teng's policies, however. The decision to move ahead swiftly on oil producton appears to have been one of several decisions reached during a series of conferences on economic issues held by the top leadership last May.
